Release Areas W12-10 to W12-14 are located on the Exmouth Plateau, a deep-water marginal plateau of the Northern Carnarvon Basin. The plateau hosts numerous giant to supergiant gas fields, and has recently become Australia’s premier deep-water gas exploration province. Some of the inboard gas fields are currently being developed or are in advanced stages of development planning.

The plateau comprises a thick pre-rift section of block-faulted, Permo-Triassic sediments overlain by thinner Jurassic–Lower Cretaceous syn-rift and thin, condensed, post-rift sediments. Top Triassic fault blocks and their associated overlying drape features, as well as deeper intra-Triassic cross-faults, provide numerous proven structural traps. Proven stratigraphic traps include Lower Cretaceous basin floor fans and Upper Jurassic shoreface sandstones while Upper Triassic pinnacle reefs represent a potential new play type.
